Flow Controls Push To Connect Fitting

Pneumatic Flow Control Valves with Push-to-Connect Fittings

Pneuforce pneumatic flow control valves are designed to precisely control the speed of pneumatic cylinders and actuators in compressed air systems. Featuring integrated push-to-connect tube fittings, these compact speed controllers simplify installation while providing accurate and repeatable cylinder speed adjustment for industrial automation, packaging machinery, robotics and OEM equipment.

Flow controls are typically installed directly on the cylinder ports and are most commonly used in a meter-out configuration where exhaust air is restricted. This method provides smooth cylinder motion, improved positional control and reduced shock loading at the end of the cylinder stroke.

Flow Control Valve Features

• Integrated push-to-connect fitting design
• Precise cylinder speed adjustment
• One-way flow restriction
• Free flow in the opposite direction
• Suitable for single and double acting cylinders
• Pressure range up to 150 PSI
• Vacuum service capability
• Compact installation directly on cylinder ports
• Available in inch and metric tube sizes
• Ideal for industrial automation systems

What Is a Pneumatic Flow Control Valve?

A pneumatic flow control valve regulates the flow rate of compressed air entering or leaving a pneumatic actuator. By controlling airflow, the speed of cylinder extension and retraction can be adjusted to achieve smooth machine operation and consistent cycle times.

Flow controls are among the most commonly used pneumatic components for controlling actuator movement in automation systems.

Flow Control vs Needle Valve

Although they appear similar, a pneumatic flow control valve is not the same as a needle valve. A needle valve restricts flow in both directions, while a pneumatic flow control contains an internal check valve that allows unrestricted flow in one direction and adjustable restriction in the other.

This one-way control is what makes pneumatic flow controls ideal for cylinder speed adjustment applications.

Meter-Out vs Meter-In Flow Control

Most pneumatic cylinders are controlled using a meter-out configuration where exhaust air leaving the cylinder is restricted. This provides smoother operation and better control, especially on double-acting cylinders.

Meter-in control restricts incoming air and is generally used only in specialized applications where cylinder loads and operating conditions permit.
